Recent advances in computational fluid dynamics (CFD), the availability of supercomputing power and the current understanding of the ureter make a realistic computational model of a ureter feasible. This study is aimed of developing a computational model of the ureter to examine urine flow. We use the in-house CFD code CgLes which is a highly parallelised three–dimensional fluid solver with sec...

In the present study, we report the case of a 69-year-old female who developed urinary leakage following partial nephrectomy (PN) to remove left renal masses. The results of CT and MR urography revealed left proximal ureteral obstruction and urinary fistula. Reoperation was performed on the 16th postoperative day to explore the left kidney and ureter in order to relieve the obstruction. The lef...

A 36-year-old female patient presented with recurrent attacks of flank pain of two years duration. Ultrasound showed right hydronephrosis and dilatation of proximal ureter. Intravenous urography showed right grade 2 hydronephrosis, and the “reverse J” shape of the collecting system suggested retrocaval course of the ureter. Magnetic resonance urography showed grade 2 obstruction due to hooking ...

Ureteral duplication is a common congenital anomaly of the urinary system observed in 0.8% of autopsy series [1]. However, bifid ureter with a blind branch is a rare condition. It is three times more prevalent in women than men and is observed twice as often on the right side as on the left side [2]. It does not generally give any clinical symptoms. However, in the literature, symptomatic cases...

Background: Vesicoureteral reflux (urinary reflux) is one of the most common congenital anomalies in children. This study aimed to compare the ureteral opening distance from the midline in children with vesicoureteral reflux (VUR) and healthy children Methods: This cross-sectional study was performed on the children with pyelonephritis who were referred to Afzalipour Hospital in Kerman, Iran f...

A duplicated collecting system (DCS) is a common anatomical variant of the kidney. As surgeons now perform more donor cadaveric transplants than in the past, the discovery of an occluded DCS may occur in the post-transplant setting. Over a dozen articles have reported on the use of DCS in the renal transplant setting. However, to our knowledge, this case report is the first to describe the crea...

Background & Aims: Hydronephrosis is a common problem in prenatal and newborn infants diagnosed by ultrasonography. Bladder to ureter reflux, the upper or lower urinary tract obstruction, and neurogenic bladder are the most common causes of hydronephrosis in newborns and infants. Methods: In this study, 100 neonates and infants with hydronephrosis were observed clinically and laboratorically fo...

INTRODUCTION In males the ectopic ureter usually drains into the prostate (50%). During ureteric developement a thin membrane (Chawalla's membrane) separates the lumen of the ureter and the urogenital sinus at the point where the ureter joins the urogenital sinus. This membrane ruptures allowing urin to drain from the ureter to the urogenital sinus. The authors reported a case of renal dysplasi...
